COMBINATION BOD-BUSHING FOR LOCOMOTQVE-ENGINES;

To all whom it may concern: 2

Be it known that L EDWARD MARVIN CAR- ROLL, a citizen of the United States, residing at Port Tampa City, in theI county of Hillsborough and State of Florida, have invented a Combination Rod-Bushing for Locomotive-Engines, of which the following is a specification.

This invention relates to improvements in lubricators for'rod-bushings and pins for locomotive engines. f

rlhe invention has vide for effectively feeding the lubricant to the pin and to accomplish this in an approved and sim le manner. l,

.A further ob]ect `is to lessen expense by eliminating the necessity of .employing thev amount of brass in the formation of the lubricator or bushing as has heretofore been the case, the use of cast-steel to the extent of about onev half of its constituency being utilized vtherefor or entering into-the same, according to my invention.

The invent1on consists therefore of the instrumentalities and features of construction substantially as hereinafter fully disclosed and defined by the appended claims.

In the accompanying drawing' is illustrated the preferred embodiment of my invention wherein it will be understood that various changes and 'modifications may be made as to details of construction and arrangement of parts without departingl from the scope or breadth of my claims, and in which drawing- Figure l is a front elevation of so much of an engine rod bushing, embodying my invention. Fig. 2 is a vertical transverse section of the same.

t will be understood that similar reference characters are employed in the two {igures'of the drawing to indicate like parts.

ln carrying out my invention, l provide an outer bushing or annulus a of cast-steel, the same constituting about one half of the structureor device and an inner bushing or 'annulus 7 of brass. rEhe outer bushing a inch deep and'about one fourth of an inch- Speeication of Letters Patent.

for its object tolpro` the engine-rod at numerous points so that ,the same will be properly distributed thereon as presently explained. f

A casting B, constituting a lubricantholding chamber or reservoir upon the rod A, provides for feeding lubricant by gravity into tha longitudinal channel E of a keeper or plug D threaded with the rod and having its inner end entering. an aperture ofthe annulus or bushing L and whereby the latter is retained in place, said channel t of the keeper or plug D, accordingly providing for feeding or delivering lubricant into the duct or groove c of the annulus or bushing. The annulus or bushing b is funcf tionally retained in effective position within the `bushing or annulus a.

I claim:
